WEAPON SIGHT
A handgun may include a slider-integrated active illumination sight. By integration of electrical connectors into the slider that conduct power from a rear powered sight to a front sight mounting area, a light source inside the front sight can emit light to the shooter's eye and make the front sight visible in any light condition. In combination with actively illuminated rear sight marks, the user now sees three evenly illuminated aiming marks. Alternatively, light can be conveyed from the rear unit to the front aiming marks by means of fiber optics.
This application claims priority to U.S. provisional patent application Ser. No. 63/244,961, filed 16 Sep. 2021, the contents of which are herein incorporated by reference.
FIELD OF THE INVENTIONThe present invention relates to sighting devices used on small arms. More specifically, it relates to illuminated open sights used on handguns or other small arms.
BACKGROUNDOpen sights are widely used, which enable the user to aim with the help of a front sight with one circular mark and rear sight with two circular marking points. For better visibility, these target marks can be equipped with bright, reflective, self-illuminated or light-collecting elements.
Open sights have many advantages: they are inexpensive to produce, uncomplicated to use, sturdy, lightweight and resistant to environmental conditions. Over the years, many developments have been made in the art with the goal of developing an illuminated open sight which can be used in low light or night time conditions. An early example is U.S. Pat. No. 2,529,057 granted on Nov. 7, 1950. This patent discloses an illuminated gun sight which uses a small battery-powered electric light bulb. Similarly, U.S. Pat. No. 3,698,092 granted on Oct. 17, 1972 introduces an illuminated open sight that uses light bulbs both in the front sight and in the rear sight. In this patent, the front sight's light source is connected to the rear sight via a wire.
More recent prior art pertaining to this subject include U.S. Pat. No. 6,640,482 issued to Carlson on Nov. 4, 2003. This patent teaches a dual-powered fiber optic sight for guns which can be illuminated either by ambient light or by a light source such as a Light Emitting Diode (LED). Ambient light and light from the LED are carried by a fiber optic rod and the rod appears as a bright dot on the front sight of the gun. In '482, the battery and the electronics are all put inside a single compartment at the front sight. While this is acceptable on a weapon with a long and relatively large barrel, it is not a viable solution for a small weapon such as a handgun.
Another recent prior art is the electronically illuminated open sight introduced in the patent application by Jones (US Pub. No. 2017/0016697 published on Jan. 19, 2017). In '697, LEDs are used to illuminate fiber optic rods positioned within both the front sight and the rear sight. Each fiber optic rod is viewable through a viewing port in the rear surface of its respected housing, making the illuminated fiber optic rods viewable only to the user of the handgun or rifle. The LEDs are housed within the sight body. Fiber optic cables are run from the LEDs to the illuminated rods in order to transfer light from the LEDs to rods which then serve as illuminated aiming marks. While this is an elegant solution, it is not easy to adapt to handguns having different barrel lengths. For different barrel lengths, custom fiber optic cables must be developed to transfer light from the rear sight to the front sight. Furthermore, the exposed fiber optic cables are prone to damage, especially during holstering.
It is evident from the above review of the state of the art that there is a need for an improved compact and illuminated open sight that can be readily mounted onto handguns.

The above description sets forth, rather broadly, a summary of one embodiment of the present invention so that the detailed description that follows may be better understood and contributions of the present invention to the art may be better appreciated. Some of the embodiments of the present invention may not include all of the features or characteristics listed in the above summary. There are, of course, additional features of the invention that will be described below and will form the subject matter of claims. In this respect, before explaining at least one preferred embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of the construction and to the arrangement of the components set forth in the following description or as illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part of this application. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.
A slider-integrated active illumination sight will be described herein. By integration of electrical connectors into the slider, a light source inside the front sight can emit light to the shooter's eye and make the front sight visible in any light condition. In combination with actively illuminated rear sight marks, the user now sees three evenly illuminated aiming marks. Alternatively, light can be conveyed from the rear unit to the front aiming marks by means of fiber optics.
On the top of the weapon slide 110 at a front end of the slide 110 is a front illuminated sight 120 having a front sight mark 122. On top of a rear end of the slide is a rear illuminated sight 130 having a pair of rear sight marks 132, 134. The front sight mark is substantially centrally located on a longitudinal axis of the weapon slide 110. The rear sight marks 132, 134 are substantially equally spaced either side of the longitudinal axis of the front illuminated sight 110 and a rear illuminated sight 120. Thus, when viewed along the longitudinal axis of the slider, the front aiming mark 122 will appear between the rear aiming marks 132, 134.
The rear sight 130 may optionally include red dot optics 140. The red dot optics may be detachable.
The rear sight 130 may optionally be charged by an inductive charging unit (ICU) 150 or an alternative wireless charging system.
A connector element 160 including a conductor may be disposed within the body of the weapon slide 110 and extend between the rear sight 130 and the front sight 120. The conductor may be an electrical conductor or a light conductor, such as an optical fiber.
The front sight 120 includes a front sight housing 124 that houses a front LED 125. A light diffuser 126 may be disposed in the front sight aiming mark 122. A front sight fastener, such as a screw 127 may mount the front sight housing 124 to the front sight mounting area 112 through the screw hole 113. The front LED 125 is mounted within the housing 124 such that light emitted by the front LED 125 is diffused through the diffuser 126 and projected rearward through the front sight mark 122. The LED 125 thus illuminates the front sight mark 122.
The front sight 120 may optionally include a thermocouple 129 that generates electricity from heat generated through operation of the handgun. The thermocouple 129 may conduct the electricity to the LED 125.
The rear sight 130 includes a rear sight housing 131 including screw holes 135 that enable the housing 131 and rear sight components to be mounted to the rear sight mounting area 116 by screws 133 into the threaded screw holes 117 of the rear sight mounting area 116.
Within the housing 131 there may be an electronics PCB 137 and a battery 138. The battery 138 may be a rechargeable and/or replaceable lithium ion battery. In one embodiment, the battery 138 may be able to be inductively charged. The PCB 137 may control the functions of the sight and may include components for near-field communications, including BLUETOOTH™. The PCB 137 may also include sensors such as motion sensors, recoil sensors, usage sensors, etc. These sensors can detect discharge of the handgun and be used to maintain a shooter's log within the PCB. The PCB may also include controls for date and time setting, as well as controls for adjusting the LEDs. The PCB also directly supports the rear LED 139 that provides the light source for the rear aiming marks 132, 134.
The rear LED 139 projects through a hole 1310 in the housing 134. An aiming mark housing 1320 is received within a groove of the housing 134 that is disposed above the rear LED 139. The aiming mark housing 1320 contains the aiming marks 132, 134 and houses a diffuser 1322. The diffuser 1322 receives light from the rear LED 139 and conducts it to the aiming marks 132, 134. Thus, the rear LED 139 simultaneously illuminates both of the rear aiming marks 132, 134.
On a side of the rear sight housing 134 there may be buttons 1340 that connect to the PCB 137 and allow for control of the functions of the sight.
As stated above, the sight may optionally include red dot optics. The red dot optics may include a detachable red dot housing 1360 that includes red dot glass 1362. The red dot glass 1362 will typically have zero parallax, as is known in the art. A red dot LED 1364 may be mounted on a diode holder 1366. The red dot LED 1364 projects a red dot onto the red dot glass 1362. A vertical adjustment screw 1350 may control the vertical adjustment of the diode holder 1366. Similarly, a horizontal adjustment screw 1370 can adjust the horizontal position of the diode holder 1366 against the action of a spring 1372.
In one embodiment, the connector element 160 may be a FFC type flexy cable. Each end of the connector element 160 may include a FFC type connector that enables a simple plug and lock connector to the PCB 137 at one end and the front LED 125 at the other end.
In one embodiment, a channel may be provided within the slider 110 to accommodate the connector 160. A conduit or passage 115 between the upper side of the slider 110 and the underside of the slider body may convey the connector 160 through the slider body to the channel. The connector 160 may first be connected to the PCB 137 board via an FFC cable plug. The connector may then be placed through the conduit 115 and into the channel inside the gun slider and connected to the front LED 125 at the front end of the slider. The channel may be covered with a heat resistant glue, epoxy, etc. that secures the connecter 160 in place so that all connector surfaces are covered and fixed to the slider body, making the connector heat, water and shooting resistant. While a specifically provisioned channel is described, alternatively, the connector 160 may be secured to an inside surface of the slider 110.
The PCB 137 may include one or more processors and one or more memories operatively associated with the processors. The processors may be programmed for a variety of functions including, without limitations, motion detection, position detection, controlling the light intensity, processing the sensor data, wireless connectivity, date and time functions, smart charging functions. The memories may store user settings, including preferred light intensities, shooting logs, etc.
As described above and shown in
In the embodiments described, the battery unit is provided in the rear sight and power is conducted forward from the rear unit to the front unit to power the diode of the front sight. This embodiment is considered preferable for balance and stability of the handgun because it reduces the cantilevered weight of the handgun. However, in an alternative embodiment, the front sight may incorporate the battery unit with power being conducted to the rear unit.
In the embodiments described and illustrated, the front sight includes an LED that is powered by current transmitted through the connector element. In an alternative embodiment, the connector element may include an optical conductor such as a fiber optic cable. The light source for the front sight may be provided in the rear. That is, the front sight may omit the LED 125 and instead, light may be conducted through the connector element to the front sight for projection rearward from the front sight.
Although the description above contains many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the embodiments of this invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.
